We present new constraints on the mass mντ of the tau neutrino and its mixing with a fourth generation neutrino. From an analysis of the partial widths of tau lepton decays we obtain the following bounds at the 90% confidence level: mντ < 32 MeV and sin2θ< 0.007, where θ describes the Cabibbo-like mixing of the third and fourth generation neutrinos.
